SweepLSD detector achieves real-time line segment detection with minimal memory

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SweepLSD, a novel line segment detector that processes images in a single pass with minimal memory usage, operating entirely with integer calculations. This algorithm, originally conceived in 2014, has been implemented in C++ and on an FPGA, achieving real-time performance on older hardware. SweepLSD demonstrates superior speed and directional accuracy compared to existing detectors like ELSED and EDLines on various benchmarks, while maintaining competitive accuracy in applications such as vanishing-point estimation and camera-attitude determination.

    SweepLSD: A One-Pass, O(width)-Memory Line Segment Detector with an Integer-Only Streaming Core and a Real-Time FPGA Realization

    arXiv:2608.22086v1 Announce Type: cross Abstract: We present SweepLSD, a line segment detector that reads the image exactly once and emits each segment within a few rows of its last pixel passing the scan line. Every stage, including connected-component labeling and the final lin…
